This was her first experience of a home, a real home, in which there was nothing but union and content; no overshadowing fear, no horrible unspoken dread, no half-guessed secrets always gnawing at the heart. But in all this new comfort Margaret Wilmot had not forgotten Henry Dunbar. She had not ceased to believe him guilty of her father's murder. Calm and gentle in her outward demeanour, she kept her secret buried in her breast, and asked for no sympathy. Clement Austin had given her his best attention, his best advice; but it all amounted to nothing. The different scraps of evidence that hinted at Henry Dunbar's guilt were not strong enough to condemn him. The cashier communicated with the detective police, who had been watching the case; but they only shook their heads gravely, and dismissed him with their thanks for his information. There was nothing in what he had to tell them that could implicate Mr. Dunbar. "A gentleman with a million of money doesn't put himself in the power of the hangman unless he's very hard pushed," said the detective. "The motive's what you must look to in these cases, sir. Now, where's Mr. Dunbar's motive for murdering this man Wilmot?" "The secret that Joseph Wilmot possessed——" "Bah, my dear sir! Henry Dunbar could afford to buy all the secrets that ever were kept. Secrets are like every other sort of article: they're only kept to sell. Good morning." After this, Clement Austin told Margaret that he could be of no use to her. The dead man must rest in his grave: there was little hope that the mystery of his fate would ever be fathomed by human intelligence. But Margaret Wilmot did not cease to remember Mr. Dunbar. She only waited. One resolution was always uppermost in her mind, even when she was happiest with her new friends. She would see Henry Dunbar. In spite of his obstinate determination to avoid an interview with her, she would see him: and then, when she had gained her purpose, and stood face to face with him, she would boldly denounce him as her father's murderer. If then he did not flinch or falter, if she saw innocence in his face, she would cease to doubt him, she would be content to believe that Joseph Wilmot had met his untimely death from a stranger's hand.
